Application filed. January 253, i929. Serlalinlo. 834,435.

This invention relates to an improved roof flange such as is employed inassociation with a vertically disposed ventpipe extending through andabove the roof.

The principal purpose of the invention is to provide a structureembodying novel details associated and cooperating in a manner toproduce a distinguishable contribution to the art, and a simplified,economical and superior product for the trade.

In carrying out the invention I have evolved and produced a mechanicalachievement in the art wherein the details are so shaped and co-relatedas to alford a wide range of adjustment to accommodate pipes on roofs ofdilferent inclinations, and to insure the provision of a leak proofjoint, while permitting the relative movement of the vent pipe.

The more specific features will become more readily apparent from thefollowing description and drawings.

In the drawings Figure 1 is a side elevational view of a flangeconstructed in accordance with the present invention.

Figure 2 is a vertical sectional view through the same showing therelationshlp of parts more clearl and Figure 3 is a view like Figure 2showing the coupling annulus reversed in its position to change theangularity of the attaclr ing base and nipple with respect to the pipe.

In the drawings, the reference character l designates a sheet metalattaching base having a central opening surrounded by an upstanding ointmaking flange member 5. EX- tending through this opening is afrustoconical nipple 6 having a bottom. flange member 7 suitablyattached to the underside of the base. The relationship of the nipple tothe base is such that the nipple is substantially obliquely disposed butis allowed to occupy a substantially vertical position. The uppertruncated end 7 is maintained in a substantially horizontal plane andthe vent pipe 9 extends therethrough.

Telescopically and rotatably fitted on the truncated upper end of thenipple isa rigid metal annulus 10 in the form of an openendedcylinder-'11. rrpproximately' one half of the lower edge portion is outstraight across, as at 12 so that it is disposedatisub'stantia-lriglitangl'es tothe longitudinalaxis of 'he pipe 10,,The remaining half is obliquely cut-asat13',thuspermitting the annulusto occupy eitlferpfthetwo positions shown in Figures 2 and 3 or tooccupy intermediate positions. A particular feature to be noted in theconstruction of this annulus is that it is provided with oppositelydisposed internal bevels. In other words it has an upper champer and alower bevel, the upper champer being designated by the referencecharactor 14; and the lower bevel by the reference character 15. Thechamper 14. extends between the points A. and B whereas the lower bevelextends from the point B down to the point C. That portion of theinterior of the annulus where the two bevels merge into each otherprovides an inwardly projecting circumferential rib.

The malleable calking collar is designated by the reference character 16and this fits telescopically into the upper end portion of the couplingannulus 1.0. lVhen hammer-ct into place, a marginal retainingbead isformed as at 17 and this rests vlh'mly against the adjacent straightupper edge of the an nulus. The internal portion of the collar howeveris wedged or jammed between the pipe and the internal surface of theannulus and extends down and beyond the champer lat as well asdownwardly beyond the aforesaid circumferential rib. It is hereby wedgedin place and conforms to this tapered configuration, serving to securelymaintain the collar in place.

The lower bevel 15 together with the peculiarly shaped lower end portionof the annulus permits rotary adjustment and yet maintains a fluid-ti htjoint between the annulus and the nipple. In this way the attaching base4 can be adjusted angularly to accommodate pipes on roofs of differentinclinations.

A careful reading of the description in conjunction with the drawingwill enable the reader to obtain a clear understan ling of theconstruction and features and advantages of 1 this improvement.Therefore, a more lengthy description is regarded unnecessary.

Minor changes in shape, size, material and rearrangeinent'of detailscoming within the field of'the invention claimed may be re- 5 sorted toin practice ifdesired.

' We claim: In a flashing of the class described, a frustoconicalnipple, an attaching base therefor, an open-ended cylindrical annulusfitting telescopically over said nipple and having an internal upperchamfer and a lower oppositely extending bevel defining an internalcircumferential anchoring rib, and the calking collar fitting'into saidannulus and cooperable 1 with said chamfer and rib, approximatelyone-half of the lower edge portion of said annulus being obliquelyoutwith respect to the longitudinal axis.

In testimony whereof we aflix our signatures. V
